Use the area names and nearby hikers below to find each one; campsite numbers can vary between guides.
Oxygen Tank locations and prices
The prices below are current listings on the community-run Fisch Wiki, updated September 25, 2026; they are not official developer-confirmed guarantees. The hiker numbers and named areas are practical landmarks.
| Tank | Location | Nearby landmark | Listed price |
|---|---|---|---|
| Basic Oxygen Tank | Northern Summit, first camp/base camp | Hiker #2 and the Merchant, by the yellow tents | C$1,000 |
| Beginner Oxygen Tank | Overgrowth Caves | Hiker #5 and the campfire | C$3,500 |
| Intermediate Oxygen Tank | Frigid Cavern | Hiker #7, beside the campfire and Summit Rod | C$10,000 |
| Advanced Oxygen Tank | Glacial Grotto | Hiker #10, beside the campfire and Advanced Glider | C$25,000 |
How to reach the Northern Expedition
Enter the portal at X: -1733, Y: 137, Z: 3820 to reach the Northern Expedition. The mountain introduces oxygen and temperature survival mechanics. Follow the named zones and hiker landmarks as you ascend to locate each tank; area names are more reliable than campsite ordinals, which are not used consistently across guides.
How oxygen and warmth work
Oxygen drops in higher areas, and running out is fatal. Campsites have oxygen refill stations; campfires are for warmth. A Winter Cloak is recommended for managing temperature, which is a separate concern from tank capacity. The four tanks progress from Basic through Beginner and Intermediate to Advanced, but dependable current breathing durations are not established, so there is no reliable minutes-based comparison here.

Oxygen Tanks are not Diving Gear
Fisch’s Basic and Advanced Diving Gear are separate tools for underwater exploration. They do not replace the Northern Expedition Oxygen Tanks, which address the mountain’s oxygen mechanic.
Source and location caveat
The Fisch Wiki identifies itself as unofficial and community-run. Its regional and item references were updated September 25, 2026; older coverage corroborates the Basic Tank near Hiker #2 for C$1,000, but campsite numbering may differ. No official developer source confirming current tank locations, prices, or capacities is established here.
